Situation and Objectives
E. van Wijk Logistics B.V. is a haulage company based in the Netherlands operating a fleet of more than 300 vehicles. They have been approached by the Mobil Authorized Distributor Den Hartog to propose solutions to further reduce fuel consumption and minimize emission levels. In comparison with its present choice of SAE 10W-30 oil, it is to be demonstrated that the use of Mobil Delvac 1 LE 5W-30 high-performance engine oil will provide higher fuel-saving potential.
Â
Recommendations and Solutions
Mobil Delvac 1 LE 5W-30 is recommended. With regards to how a lubricant can impact a fuel economy, the most important single parameter is viscosity control. If the optimum viscosity is being utilized for each operating condition, then it will help minimize overall engine friction and reduce fuel consumption. In addition to the above, viscosity can increase over time because of lubricant break-down and contamination. Soot particles, contaminants and by-products of oil break-down can lead to oil thickening, which can potentially lead to reduced fuel economy and compromise wear protection. Hence, a lubricant must be specifically designed to resist thermal, oxidative, and soot induced thickening.

Results and Benefits
The measurement of the monthly distances travelled and fuel consumption levels for three DAF test vehicles shows that savings from 1.29% to 4.09% have been observed versus the previous consumption figured. The vehicles’ operating and weather conditions were comparable. In addition to outstanding cold-start behavior and potentially extended engine service life through reduced wear, Mobil Delvac 1 LE 5W-30 could, in those circumstances, help provide a fuel savings potential of up to 115 k EUR in the case of a changeover of all 300 trucks. This could theoretically result into a CO2 reduction of up to 265 tons per year*.
